The principle of selecting a Sorting Algorithm and Its Implementation in Python are illustrated in text and text, Basic Idea:Find the smallest element in the unsorted sequence, put it in the first place, and then find the smallest element in the unsorted sequence, put it in the second place, and so on, until all elements are sorted. Suppose there are n + 1 sequen
